Hi Michael,
No doubts that you have one of the best gallery's here on TE but it's highly underrated. Almost all your work is flawless and that has nothing to do with the Hassie (might help a bit of course), but more in dedication, patience, knowing the area, the best spot and waiting for that special moment of light....high class work..!!!
We have seen many pictures here on TE from those famous falls, they are high on my list also, but if i could make one picture that comes close to this one i would be more than happy. With other words, best shot of Iguazu without a doubt.
Take care, Henk
